TELEPHONE ATTACHMENT. I

Specification of Letters Patent.

Patented Nov. 20, 1906.

To aZZ whom it may concern:

Be it known that I, JosEPH SILVERMAN, a citizen of the United States,residing in the city and county of San Francisco and State ofCalifornia, have invented new and useful Improvements in TelephoneAttachments, of which the following is a specification.

My invention relates to a telephone attachment, and especially to ahook-operating device for use in conjunction with means for holding thereceiver in suitable relation to the mouthpiece and to the ear of theoperator.

The object of the present invention is to provide a simple andeasily-operated device for normally holding down the hook of atelephone, and which device when the hook is up will not prevent thehook being shaken or vibrated, in case it is desired to better theconnections or attract the attention of central.

The invention consists of the parts and the construction and thecombination of parts, as hereinafter more fully described and claimed,having reference to the accompanying drawings, in which Figure 1 is aside view of the device, the dotted lines representing the arm ininoperative position. Fig. 2 is a plan view partially in section, andFig. 3 isa detail showing the telephone hook and spring.

The means for supporting the receiver forms no part of the presentinvention, and hence is not shown.

A represents asuitably-supported vertical standard or rod on which asleeve 2 is adjustable with respect to the telephone hook 3.

The standard A may be applied to a handtelephone or adapted to awall-telephone, as here shown; Where used on the wall, the rod ispreferably supported in the brackets 4, be ing removably held inposition by suitable means, as the set-screws 5. This arrangement of therod and brackets allows the device to be easily and quickly placed inposition and adjusted.

The telephone is of any ordinary wellknown construction in which thehook is normally upheld to close the circuit by means of the spring 6.Instead of holding the hook down by means of the receiver when thetelephone is not in use I employ the following mechanism, which iscarried by the adjustable sleeve 2. 7 is a short rod or bar, which isadjustable in the sleeve 2 at right angles to the standard A. This barand the socket in which it slides are suitably shaped to prevent the barturning when the latter is locked in desired position by the set-screw8. One end of the bar 7 carries a projection 9, on which a lever orfinger 10 is fulcrumed, as at 11. A spring 12, having one end anchoredto the projection 9, is connected to the finger 10, so as ordinarily topull down on the finger and cause the latter to engage with the hook 3and hold the hook down to interrupt the circuit. The fulcrum end of thefinger 10 and the corresponding seat on the projection 9 are flattened,so as to provide a proper bearing for the finger about its pivot. Thepivotal movement of the, finger 10 about its pivot is limited byappropriate means, as the lug 13 on projection 9, encountering one orthe other of the stops 14 on the finger 10.

The anchorage 15 of the spring on projection 9, the connection 16 of thespring with the finger, and the disposition of the stops 14 with respectto the lug 13 are such that when the finger is lifted to disengage thehook and the lower or rear stop 14 is brought against the lug the pointof connection 16 of the spring with the finger will be carried backbeyond the pivot 11, so that the finger will stay up of its own accord.Having finished a conversation, the operator gives a slight forward anddownward pull on the finger, which carries the point 16 forward of pivot11 and allows the spring 12 to act to pull down the hook, which isequivalent ordinarily to hanging up the receiver.

If desired, the finger may be covered with a piece of rubber tubing orthe like to obviate shock and noise.

By reason of the adjustment afforded by the sleeve 2 and bar 7 thefinger can be properly and quickly positioned with respect to the hook.With the finger 10 thrown up and out of the way of the hook the latteris left perfectly free.

Having thus described myinvention, what I claim, and desire to secure byLetters Patent, is

1. The combination with a telephone-hook, of a pivoted finger, and aspring connected therewith and exerting a tension on the finger on oneside of the pivot when the finger is turned in one direction and adaptedto eXert a tension on the other side of said pivot whenothe finger isturned in the opposite direction.

2. The combination with a telephone-hook, of means for holding down thehook comprising a pivoted finger, a spring having one end suitablyanchored and the other end connected with the finger proximate to itspivot, said finger having a limited pivotal movement to divert thetension of the spring to one side or the other of the pivot.

8. The combination with a telephone-hook, of a pivoted finger, anadjustable support for said finger, a spring exerting a tension on oneside of the pivot of the finger for causing said finger normally topress down on the hook to depress the latter, and means whereby saidspring is adapted tension on the other side of said ivot When the fingeris moved, to hold the -nger in inoperative position With respect to thehook.

4E. The combination With a telephone-hook, of a vertical standard, asleeve adjustable on said standard, a bar adjustable in said sleeve, afinger pivotally supported on the bar, and a spring acting on the fingerto hold down the hook.

5. The combination With a telephone-hook, of a vertically and laterallyadjustable fingersupport, a nger pivoted on said support, a springoperating on the finger to hold down the hook, and stop means limitingthe pivotal movement of the finger.

to exert a 6. The combination with a telephone-hook,

of a finger-support, a finger pivoted on said support, a spring havingone end suitably anchored and the other end connected to the fingerproximate to its pivot and operating to exert a tension on the finger onone side of the pivot When the finger is turned in one direction and toexert a tension on the other side of the pivot When the finger is turnedin the opposite direction, and means to limit the pivotal movement ofthe finger.

7. The combination with a telephone-hook, of suitably-supportedbrackets, a standard adjustable in said brackets, a sleeve adjustable onsaid standard, a bar adjustable in said sleeve, said bar having alateral projection at one end, a finger pivoted on said projection, anda spring anchored to said projection and connected with the finger andoperative to cause the finger to hold down the hook.

In testimony whereof I have hereunto set my hand in presence of twosubscribing Witnesses.

JOSEPH SILVERMAN.
